Pan-genome Analysis of Angiosperm Plastomes using PGR-TK [PDF]

arXiv
We present a novel approach for taxonomic analysis of chloroplast genomes in angiosperms using the Pan-genome Research Toolkit (PGR-TK). Comparative plots generated by PGR-TK across diverse angiosperm genera reveal a wide range of structural complexity, from straightforward to highly intricate patterns.

Evidence for evolution of a new sex chromosome within the haploid‐dominant Marchantiales plant lineage

Journal of Integrative Plant Biology, EarlyView.
Genomic evidence suggests that sex chromosomes may not be conserved within liverworts. Re‐evolution of dioicy in the genus Riccia may have occurred with probable de novo establishment of a new sex chromosome from the autosome, and the m‐chromosomes have evolved independently from chromosomes in the Marchantiales.

Insights into the genomic divergence of maize heterotic groups in China

Journal of Integrative Plant Biology, EarlyView.
Seven core heterotic groups were differentiated in maize germplasm from China, and these groups showed regionality and uniqueness at the genomic level. The environmental adaptability of heterotic groups was improved by selection for more stress tolerance‐related genes for adaptation to the complex and changeable climate.

High‐quality genome of allotetraploid Avena barbata provides insights into the origin and evolution of B subgenome in Avena

Journal of Integrative Plant Biology, EarlyView.
A high‐quality genome sequence of the tetraploid wild oat Avena barbata provides crucial genetic information for the Avena B‐genome, allowing clarification of the evolutionary trajectories of the four subgenomes within Avena and identification of numerous key genes related to environmental adaptability, thus offering valuable resources for oat breeding

Multiscale metabolic modeling of C4 plants: connecting nonlinear genome-scale models to leaf-scale metabolism in developing maize leaves

, 2015
C4 plants, such as maize, concentrate carbon dioxide in a specialized compartment surrounding the veins of their leaves to improve the efficiency of carbon dioxide assimilation.

Genetic and morphological variation in the genus Zygogonium (Zygnematophyceae, Charophyta) from localities in Europe and North America and description of Z. angustum, sp. nov.

Journal of Phycology, EarlyView.
Abstract The globally distributed genus Zygogonium exhibits a narrow environmental range, with 19 morphologically described species. Its molecular characterization is poor, based on a single accession of the type species Z. ericetorum from Austria.

Remodeling of the terpenoid metabolism during prolonged phosphate depletion in the marine diatom Phaeodactylum tricornutum

Journal of Phycology, EarlyView.
Abstract Terpenoids are a diverse class of naturally occurring organic compounds, which derive from five‐carbon isoprene units and play crucial roles in physiology, ecological interactions such as defense mechanisms, or adaptation to environmental stresses.

The role of microbiota in kelp gametophyte development and resilience to thermal stress

Journal of Phycology, EarlyView.
Abstract Ocean warming is driving profound changes in the ecology of marine habitat formers such as kelps, with negative implications for the biodiversity and ecosystem services they support. Thermal stress can disturb associated microbiota that are essential to the healthy functioning of kelp, but little is known about how this process influences ...

Isolation and characterization of a spore development mutant in Pyropia yezoensis (Rhodophyta) induced via insertional mutagenesis

Journal of Phycology, EarlyView.
Abstract Mechanistic elucidation of spore development is essential for understanding reproductive strategies and improving seaweed cultivation. In this study, we isolated a mutant with spore development defects in Pyropia yezoensis (Rhodophyta) from among genetic transformants generated via insertional mutagenesis. We characterized the mutant phenotype

Hybridization and gene expression: Beyond differentially expressed genes

Molecular Ecology, EarlyView.
Abstract Gene expression has a key role in reproductive isolation, and studies of hybrid gene expression have identified mechanisms causing hybrid sterility. Here, we review the evidence for altered gene expression following hybridization and outline the mechanisms shown to contribute to altered gene expression in hybrids. Transgressive gene expression,
